Abstract

Perubahan iklim merupakan tantangan global yang memerlukan pemahaman ilmiah berbasis data untuk mendeteksi, menganalisis, dan memprediksi dampaknya. Artikel ini bertujuan untuk mengeksplorasi penerapan model matematika, khususnya model Autoregressive Integrated Moving Average (ARIMA), dalam memahami dinamika iklim melalui data curah hujan di Indonesia. Penelitian ini menggunakan pendekatan kuantitatif dengan data sekunder berupa deret waktu curah hujan bulanan dari stasiun meteorologi. Teknik analisis yang digunakan adalah pemodelan ARIMA yang dikembangkan dengan dan tanpa integrasi variabel eksogen seperti indeks monsun dan El Niño. Hasil penelitian menunjukkan bahwa model ARIMA mampu memberikan prediksi yang cukup akurat untuk curah hujan, terutama jika parameter model disesuaikan dengan karakteristik data wilayah tertentu. Integrasi indeks global ke dalam model juga meningkatkan ketepatan prediksi, mencerminkan pentingnya dinamika iklim regional dan global dalam analisis lokal. Evaluasi model melalui indikator statistik seperti Mean Square Error (MSE) dan Root Mean Square Error (RMSE) menunjukkan kinerja yang memadai untuk aplikasi praktis di sektor pertanian, sumber daya air, dan mitigasi bencana. Penelitian ini menyimpulkan bahwa pendekatan matematika melalui model ARIMA efektif dalam mendukung pemahaman perubahan iklim dan dapat digunakan sebagai alat prediktif untuk perencanaan adaptasi jangka pendek. Pengembangan model lanjutan disarankan untuk memperhitungkan dinamika musiman dan nonlinearitas data iklim yang lebih kompleks. Temuan ini diharapkan dapat menjadi kontribusi dalam pengembangan strategi ilmiah berbasis data dalam menghadapi tantangan perubahan iklim.

Abstract

A mentoring activity on the use of the interactive media ZEP Quiz was conducted at SDN Palrejo with the primary goal of improving teachers' skills in utilizing gamification-based learning technology. The background to this activity stems from the fact that most teachers at the school are not yet familiar with or use ZEP Quiz, despite the availability of adequate digital facilities. This minimal use of technology leads to a monotonous learning process and does not facilitate active student engagement. However, in today's digital era, the implementation of innovative learning media is crucial for improving the quality of education. The methods used in this activity included initial observations, interviews with teachers, direct mentoring, and practical use of ZEP Quiz with students in class. The mentoring was designed in the form of structured training that included an introduction to the features, the creation of questions based on Bloom's Taxonomy, and strategies for integrating ZEP Quiz into learning scenarios. The results of the activity showed a significant increase in teachers' knowledge and skills. Teachers were able to operate ZEP Quiz independently, develop questions according to cognitive level, and apply them to the teaching and learning process. The implementation in the classroom received a positive response from students, characterized by high enthusiasm, active participation, and a fun, competitive atmosphere. These findings support previous research on the effectiveness of gamification in improving student motivation, engagement, and learning outcomes. In conclusion, mentoring the use of ZEP Quiz has proven effective in strengthening teacher competency while creating interactive learning that motivates students. Going forward, innovative and sustainable efforts are needed, including varying question content, developing gamification strategies, and integrating with other digital platforms, to avoid declining motivation due to the novelty effect and ensure the sustainability of technology-based learning in schools.
